Kachelus is a ring of many small worldlets (planetoids AKA an "asteroid belt"), not capable of retaining an atmosphere or water, and are both non-agricultural and nonindustrial in nature.

These worldlets warrant hazardous environment precautions.

Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.

They require extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.

The worldlets are, for the most part, unable to produce quality foodstuffs and must import them.
